I just got a dual 200 Mhz 604e card for an older PowerMac, and I installed 
and started compiling 2.0. Just as I expected, I got a panic after a few 
hours. The first bit of text got cut off because of the serial console, 
but the traceback is similar to other SMP panics:

0xd54d3d90: at panic+0x19c

             r1=0xffffe210 cr=0x20002044 xer=0 ctr=0x41901b04

Anyone have a clue about why we're seeing this?
